1.0 Introduction
The active loop antenna ALA.01 is best suited for applications where omni-directionality is
important. The average gain is similar to an 18mm active patch antenna but in a much narrower
profile, only 2.3mm at its highest point, allowing this antenna to be used perpendicular to the
device main-board, or placed adjacent to the top or bottom of device main board. A one stage
LNA combined with a SAW filter boosts the S/N (C/N) of the GPS system and helps to overcome
some noise effects from today’s crowded device boards that passive antennas cannot resolve.
The antenna can be placed in a plastic slot in the device housing. Alternatively adhesive foam,
hot-melt, or non-conductive screws could be used to mount the antenna. The core antenna
design principle of loop current flow tends to “lock-out” a lot of surface noise from close circuitry
from entering the antenna.
